2 Claims.

This invention relates to improvements in windows. It is an object of the invention to provide awindow which is cheap and simple to manufacture and which lends itself to mass production methods.

Another object of the invention is to provide a window wherein means are provided for firmly supporting a pane in a sash. in such a manner that the pane may be easily removed and another substituted therefor.

Further objects of the invention are to provide a window wherein airtight-joints are made between the sashes and their guides thus rendering weather stripping unnecessary; wherein the and 3-3 respectively of Figure 1, on an enlarged scale.

Figure 4 is an outside elevation showing a slightly modified form of the window.

Figures 5 and 6 are enlarged sections on the lines 5-5 and 66 respectively of Figure 4.

Figure '7 is a detail showing one corner of the sash shown in Figures 5 and 6.

Figures 8 and 9 are enlarged partial elevations showing a top and a bottom corner respectively of the window shown in Figures 1 to 3.

Figures 10 and 11 are enlarged partial eleva tions showing a top and a bottom corner respectively of the modification shown in Figures 4 to '7.

Referring to the drawings, I designates a conventional rectangular frame consisting of four members 2 welded to one another at their adjacent extremities which are usually cut at 45 degrees as shown, and formed along the inner and outer extremities of the members are outwardly directed flanges 3 and 4 spaced a distance equal to the thickness of the wall in which the frame is g to be mounted.

The parts mounted in the frame I may consist either of somewhat resilient steel, preferably either stainless or rustproofed, in the form shown in Figures 1 to 3 and 8 and 9, or of a suitable alloy and made according to the modified construction shown in. Figures 4 to 7 and-10 and 11.

Referring first to Figures 1 to 3 and 8 and'9, mounted on the inner faces of the vertical frame members 2 and extending throughout the entire length of the latter are opposed vertical sash guides 6 each of which consists of a. single piece of material having a flat portion I centrally of its width which rests against the said frame memhere. At both extremities of the flat portion 2 the material is folded back upon itself for a short distance as shown at 8 and is then forwardly folded to form arms 9 which terminate in trans.- versely cupped inner and outer stile groove portions In and II. The guides 6 are suitably secured to the inner faces of their respective vertical members in any suitable manner, in the present instance the members 2 are apertured and have nuts 6| welded on their outer faces; bolts 62 extend through the folded extremities of the guides 6 and through the member apertures and are in threaded engagement with the nuts 6 l By thus forming the stile groove portions [0 and I I along the opposite longitudinal margins of the guides 6 suflicient resilience is provided between opposed pairs of inner and outer stile groove portions both to support the lower and upper sashes l2 and I3 respectively at any desired height without the use of cords and sash weights and to per,- mit vertical movement of the sashes without the exercise of undue effort.

Mounted on the inner faces of the upper and lower horizontal frame members 2 are receiving elements M and i5 respectively, which may be secured thereon by screws 63 in threaded engagement with nuts 64 welded to the outer faces of the said frame members. The upper receiving element It has a flat intermediate portion l6 which rests against the upper horizontal member 2. This portion It at both extremities is folded back upon itself at H for a short distance. From the outer fold I! a downwardly projecting arm l8 extends and from the lower extremity of the latter a transversely cupped portion l9 extends inwardly to receive the upper margin of the upper sash l3. From the inner extremity of the cupped portion IS! an upwardly directed arm 20 extends which terminates in a foot 2| slidable upon the lower face of the fiat intermediate portion l6 toward its inner folded extremity Ila which is spaced from the said foot. It will be noted that the arms l8 and 20 are downwardly somewhat inclined. toward one another to render the cupped portion I9 more resilient and more readily flexible upon contact by the sash l3 when the latter is raised against it. The lower receiving element I5 is the same as the element l4 above described when turned upside down and with the cupped portion IS in position for contact by the lower margin of the lower sash l2 when closed.

The upper and lower sashes l3 and l 2 are identical in construction and each consists of four rails 22 of the same cross sectional form which are preferably cut at 45 degrees at their extremities and welded to one another. Each rail 22 consists of a relatively thin piece of steel shaped in the following manner: Intermediately of its width the rail is semi-circularly curved to form a convex back 23 the curvature of which conforms to that of the concave transversely cupped stile groove portion l0, H, l9 or l9a which itis to engage. Extending forwardly from opposite sides of the convex back 23 are .parallel outer and inner walls 24 and 25, the former beinglonger than the latter and the forward edge of the inner wall extending to one longitudinal edge of the material. The outer wall 24 at its forward extremity is inwardly and rearwardly stepped-at 26 and 21 respectively so that the inward step forms a bearing ledge to support one outer edge of a window pane 28. At the rearwardextremity of the ledge or step 21 the material is. inwardly folded to form a rest 29 which extendsparallel and contiguous to one edge face of the pane 28, and extending from the inner extremity of the rest 2-9 is a rearwardly folded lip 39 which lies adjacent but'outwardly-relative to the inner wall '25 so that' the'rear longitudinal margin of a removable supporting-plate 3| is resiliently held betweenthe said lip and the wall 25. I prefer that the margins of the panes be mounted in suitable grooved packing strips 32 which bear against the'r-ests -29 and'are held between the ledges 2'! and the movablesupporting plates 3 l. Moreover to simplify the insertion and removal of the latter they' are made-somewhat shorter than the sash railsin which they are mounted.

Thearrangement shown in Figures 4 to '7 and lll and ll is'substantially the same as that already described. 'The vertical sash guides ta each consist of a fiat portion la integral with which adjacent their extremities are forwardly inclined arms'Bawhich terminate in transversely cupped inner and-outer stile groove portions 48a and i la. {The upper and lower receiving elements Ma and 1 a which are both the same include fiat portions orbases lSa and-a single forwardly inclined arm :50 "to-support the transversely cupped portion b.

The rails 22a forming both the upper and lower sashes 13a and i-Za are again identical and "each rail includes-a single member having a substantially semi-circular back 23a, a forfwar'dly projecting wall 24a flush with the outer face-of the member and forming a ledge 21a along the inner side of-the projection. A rest 29a for the window pane 28 is formed by the inner face ofth'e member inwardly of the ledge 27a, and spaced inwardly of the latter a groove 33 is fornied in theraibto receive a removable supporting plate-3i a. The margins of the pane 28 are again preferably mounted in suitable packing strips 32awhich bear against the rest 29a and :are held betweenthe ledge 27a and the removiable'plate 3-la.

"Only certaiifalloys are suitablefor the manufacture of these sash guides Ea, upper and lower receiving elements 14a and 15a and sash rails 12a "as all these parts should be somewhat resilient. The transversely cupped stile groove portions Illa and I la should be sufficiently resilient'to support the sashes without the aid of sash cords and weights and also to make sufficiently tightjoints with the rounded backs of the sash rails to render weather stripping unnecessary; there should be enough give in the cupped portions Nb of the elements Ma and i5a so that a tightweather resistant joint is made withthe adjacent sash rail when the sash is closed; and thesash rail material should be such that the removable supporting plates 3Ia are firrrily engaged inthe grooves 33.

owing to the fact that the materials preferable for use for the sash rails 22a is difiicultand expensive to weld orbraze, and also to reduce newer-gm of therails, longitudinal apertures "35 are formed through the said rails, and their adjacent extremities are securedtoone another by then secured through each rail and the leg of v the angle plates extending thereinto.

While in the foregoing the preferred embodime'nts of the invention have been described and shown, it is understood that further alterations and modifications may be made thereto provided the said alterations and modifications fall within the scope of the appended claims.

What I claim is:

"'1. 'A double hung window sash construction "consisting of vertical sash guides and slidable sashes cooperating therewith, each guide'having a base forattachment to a window frame, forwardly'projecting arms integral witheachguide extending from the base adjacent the inner "and outer sides of the latter, and a transversely cupped stile groove portion having a concave bearing surface extending from and integral with the forward "extremity of "each arm throughout the length of the latterjthe stile groove portions on each guide being intransverse alignment and spaced from and adjacent one another for independent movement at a position in advance of said base, each stile groove portion on one guide being opposite on stileygroove .portion on the otherv guide and said stile groove portions and their arms being resilient so astourge'said sashes into close engagementwitheach other, each sash including vertical rails having convex backs the curvature of which corresponds to that "of the cupped stile groove portions mounted for vertical movement in andresiliently and frictionally-en gaged between opposed pairs of transversely cupped stile groove portions said rails being so seated in said stile groove portions that the said stiles engage eachotherso as to effect a sealing contact thereb'etween.
